Get only city names with Google Maps API autocompletion

Question

I use this code to provide autocompletion of location names thanks to the Google Maps API:

var autocomplete = new google.maps.places.Autocomplete(document.getElementById('adr'));

City : <input id="adr" type="text" class="form-control" value="" >
<script src="http://maps.googleapis.com/maps/api/js?sensor=false&amp;libraries=places" type="text/javascript"></script>

All locations names are provided, like city names "Paris", but also country names "Germany", region names, etc.

How is it possible to have autocompletion but for city names only? i.e. no street names, no country names, no region names ?

Solution

That's in the doc : https://developers.google.com/places/documentation/autocomplete#place_types

var autocomplete = new google.maps.places.Autocomplete(yourHTMLElement, { types: ['(cities)']});
